Albus doesn't have mana cost related to his abilities, instead, he uses his secondary bar for his unique resource: Balance. Albus starts the game with this bar on Balance and it changes to Order or Chaos depending if he deals or receive damage.

Abilities

Power of Order

Every time Albus Receives damage he will gain 5 Chaos, increasing his Attack damage and Ability Power by 1 / 1.5 / 2% up to 10 / 15 / 20%, while reducing his defensive stats by half of that percentage.
Contrary, everytime Albus damages an enemy, he will gain 5 Order, increasing his Armor and Magic Resistance by 1 / 1.5 / 2% while reducing the damage he deals to target's under 50% of max health by 5% per every 25 Order.
